Inkscape encountered an internal error

Hello,
I am normally working on Inkscape 0.46using the Ubuntu Operating System and this version of Inkscape is unable to export all features well to a PDF therefor I thought to use Dev version but I got an error message when I start this version to continue my work. You can see the error message so please guide me to resolve this issue as soon as possible. Thanks in advance.

Inkscape encountered an internal error and will close now.
